Description
Technical field
The present invention relates to display technology field, more particularly to a kind of production method of flexible display.
Background technology
Flexible display technologies were having development at full speed in recent years, thus drove flexible display from the size of screen to aobvious
The quality shown all has made great progress.The cathode-ray tube that the disappears still liquid crystal display of mainstream now is either on the verge of,
Inherently belong to traditional rigid display.Compared with traditional rigid display, flexible display has many advantages, such as,
Such as impact resistance, shock resistance is strong, light-weight, small, carries more convenient etc..
Since the flexible materials such as PI are flexible, therefore need with the hardness such as glass height, be not easy in TFT-LCD/OLED processing procedures
Curved base material completes the making of TFT-LCD/OLED processing procedures for carrier, completes to need base material and flexible substrate point after making
From.Traditional separate mode is divided into physical separation mode and separation by laser mode.For physical separation mode, its cost is low, but right
The circuit that flexible surface is made influences big, easy damage destruction display element, reduces the yield of product;For separation by laser mode,
Its survivable display element, but equipment cost is high, and cost of equipment maintenance is high.
The content of the invention
The defects of in order to make up prior art, the present invention provide a kind of production method of flexible display, do not damage flexibility
The components such as the circuit made by material and flexible surface, improve product yield, reduce cost.
The technical problems to be solved by the invention are achieved by the following technical programs:
A kind of production method of flexible display, includes the following steps:(1)Flexible substrate is made on the glass substrate, in flexibility
Various display elements are made on substrate;(2)The glass substrate is etched away using etching liquid, to realize flexible substrate and glass
The separation of substrate.
Further, the etching liquid includes the mixed liquor of hydrofluoric acid, hydrochloric acid and sulfuric acid, wherein, hydrofluoric acid, hydrochloric acid and sulphur
Acid volume ratio be:(6~8):(2~3):(1~2).
Further, the concentration of the hydrofluoric acid is 5%~20%, and the concentration of the sulfuric acid is 95~98%, the hydrochloric acid
Concentration is 32~37%.
The etching formula of liquid of the present invention is reasonable, and each component cooperates, synergistic effect, and efficiently advantageously glass can be carried out
Etching, and etching speed is faster.
Further, step(2)In carry out at normal temperatures.
Further, the material of the flexible substrate is the one or more in PI, PET, PC, PES, PEN.
Further, in step(2)Before, it is additionally included in the one side that the glass substrate is in contact with the flexible substrate
Make protective layer.
Further, the material of the protective layer is fluorocarbon solvent or esters solvent;Made by the way of coating described
Protective layer.
Further, the flexible display is flexibility TFT-LCD or flexibility OLED.
The present invention has the advantages that:
The etching liquid energy of the present invention efficiently advantageously performs etching glass, and etching speed is faster;Protective layer is added to be carved
Glass is lost, flexible substrate surface is easier to be protected, survivable.The raw materials used present invention is all commercially available product, and cheap,
It is readily available, on the premise of flexible substrate is not damaged, can realizes the separation of flexible substrate and glass substrate, improves production effect
Rate, improves product yield, reduces production cost.
